2 Claims.

'Ihis invention relates 130 measuring devices particularly to devicesthat may be associated with containers for delivering a measured.quantity of the material contained in said container,

5 as f02 instance a dose of head-ache remedy or other medicines ormaterials usual1y dispensed at drug stores and ofher places where apredetermined quantity of such material is desired tobe dispensed foreach dose, portion or drink.

An object of the invention is 110 provide a novel device that may beused as an attachxnent for bott1es or containers and. in which thematerial in the container is sea1ed therein and the measuring chamberwhen noc in use is open to the atmosphere so as to prevent the materialfrom becoming dampened in the measuring chamber, which will likelyresul1; in swelling of the material and resultant clogging of thedevice.

An object is 130 provide a nove1 -device of the above character whichWill efiectively sea1 the material in the container after a measuredquantity thereof has been dispensed.

Another object is to provide a novel measuring device which after ameasured quantity has been dispensed Will automatically be maintained ina position in Which the measuring chamber will be opened to theatmosphere.

A still further object of the invention is to provide a nove1 measuringdevice that may be manually operated to dispense a measured quantity ofmaterial to be dispensed and. which Will have a snap action indispensing the material whereby the likelihood of granules of thematerial being dispensed remaining under the valve and preventing anefiective seal wi11be recluced to a minimum, and which snap action Willalso prevent the va1ve and trap door remaining open for such period cftime as may permit the material in the container to flow past the trapdoor in any amount other than the predetermined and measured quantitydesired.

A still further object is to provide a novel attachment of the abovecharacter that is simple, economical of manufacture, easy t0 operate andwhich may be associated With frames and stands at present being used inconjunction with devices of analogous character.

Yet a further object is to provide a nove1 combined stopper for theopening of a container 50 which Will permit the contents thereof to besuccessively dispensed therefrom in measured. quantities and which Willprevent delivery or spilling of the contents of said Container in theevent the container should. be accidentally tipped over.

The invention comprises the constructions,

combinations and arrangements of parts, more particularly hereinaftersei; forth in the following specification and. pointed out in theclaims.

Other objects, advantages, and features of invention may appear from theaccompanying drawing, the subjoined detail description and the appendedclaims.

The aecompanying drawing illustrates the invention in some 0f the formsI at present deem preferable.

Figure 1 is a front elevation 0f a measuring device embodying myinvention. Dot and dash lines indicate the mouth or opening of acontainer with which it is adapted to be associated. Parts of thecontainer are broken away 130 contract the v1ew.

Figure 2 is a side elevational view of my measuring clevice shown inFigure 1 and looking from the right toward the 1eft in Figure 1.

Figure 3 is an axial sectional vievv taken on line 33 Figure 1, butshowing the device in position to receive a charge from the container.

Figure 4 1's a bottom plan view of the device shown in Figures 1-3 andWith the parts in the same position as shown in Figure 3. Parts arebroken away to contract the view.

Figure 5 is a modified. form of my invention and in Which the dispensingvalve is operated in a reverse direction to that shown in Figures 14 andin this Figure 5 the valve is shown as being operated to permit themeasuring chamber to be filled after which 1;he valve automaticallycloses to the position shown in dot and dash lines.

- Figure 6 is a transverse sectional view taken on line 6-6 Figure 5.'Parts are broken away to cor1tract the v1ew.

Referring to Figures 1-4, I indicates the open end 01 mouth 015 a bottleor container wih which my measuring and. dispensing device A isassociatecl and which comp=rises a housing 2 that is provided. With anaxial bore 3 which forms a measuring chamber of a predetermined capacity1:0 receive a charge or dose frorn the container I. The housing 2 isprovided with an annular fiange 4 that is adapted to be received in asupporting frame (not shown) and upstanding from the fiange 4 1's a neckportion a that receives a gasket 5 of rubber or other suitable materialto form an effective air tight sea1 with the mouth or opening of thecontainer I.

Extending from.the underside of, and ab the rear of the flange 4 is aplurality of bosses 6 that form bearings for a shaft 1 130 which thetrap door 8 is pivotally connected and to which a yoke 9 is fixed by anysuitable means as by a pin I0.

The trap door 8 is provided with upstanding side flanges II that confinethe ingredients into a predetermined path while the same are beingdispensed. An upstanding 1ug I2 is also provided on the door 8 and towhich a connecting 1ink I3 is pivotally connected at one end and which1ink I3 is secured in any suitable manner a1: its other end to a va1veI4 by any suitable means as by the p1ug I5 that is threaded into thevalve I4. The link I3 is provided intermediate its ends with a coiledportion I6 ohat is preferably formed in the concave underside of thefrusto conical valve I4 and which provides a resilient spring means thattakes up the shock of the snap action of the valve operating mechanism Bthat Will be more fully hereinafter described Guide pins o1 members IIextend downwardly from the valve I4 and slidably engage the side wal1sof chamber 3 to guide I he valve I4 away from and toward the valve seatI8 against which the vaive I4 seats and makes an air tight fittherewith.

The valve operating mechanism B comprises the shaft I to which anoperating 01' handle memher I9 is fixed and a spring 28 has one endconnected 110 the fiange 4 and the other end thereof 120 the member I9so that 1:he shaft I and yoke 9 Will be normally forced into oned.irection to normally maintain the trap door 8 in open position and thevalve I4 in closed position. The yoke 9 is provided With a depending 1ug20 that is provided With a recess 2I into which one end of a springmember 22 is received and the other end of said spring member 22 isreceived in a recess 23 that is formed in an upstanding lug 24 that isconnected to the trap door 8.

In the modification shown in Figures 5 and 6 the analogous parts aregiven the Same numbers With an exponent and therefore furtherdescription of the same parts will not be necessary.

However, the valve I4 is connected to a U-arm 25 that is formed by theribs 26 on door 8 and the connecting arm at the outer extremitiesthereof by the ]ink I3 that is secured to one end 015 the valve I4 inany suitable manner as by threading the same thereinto, as shown, andthe guide pins or posts I'I' are extended from the opposite sides of theparts c and d that are threaded or otherwise secured together as at; e

to form the measuring chamber 3'.

In operation of the device shown in Figures 14 the valve I4 is normallyin closed position as shown in Figures 1 and 2, and in order to dispensea measured quantity f the ingredients in the container I the handlemember I9 is moved forwardly, as viewed in Figure 1, thereby oscillatingthe shaft I forwardly and I;he yoke 9 rearwardly, and as a resu1t ofsuch operation a tension Will be built up in the spring 22 that the sameWill be exerted against the lug 24 and. due to the oif-center positionof yoke I9 and 1ug 24 will cause the door 8 1:0 be oscillated aboutshaft I to move the trap door 8 against the lower end of the housing 2and effectively seal the same against contents 0f the Container escapingpast the door 8 and at the same time the valve I4 will be raised topermit flow of gravity of the contents of the container I into I:hemeasuring chamber 3. Upon release of the handle mernber I9the spring 28will automatically urge the shaft I in a reverse direction to move theyoke 9 in a reverse direction with respect to its pivotal connectionWith shaft I so that the tension created in spring 1 22 will be exertedupon lugs 24 to cause the door 8 to be opened and through the link I3110 move -receives a lug (not shown) on a stand (not shown) with whichthe measuring device may be associated, and the fiange 4 is alsoprovided with recesses 3I With which screws cooperate to maintain thedevice in proper position relative to a supporting stand that iscommonly used for supporting and holding a device of this character.

In the operation of the device shown in Figures and 6 When the handlemember I9 is moved forward the va1ve I4 is moved downwardly as shown inFigure 5 and the measuring charnber 3 is filled With ingredients fromthe container I and upon release of the mernber I9 the valve I4 willautomatically be moved to the dot and dash line position shown in Figure5 to seal the contents of 'ohe con tainer therein and release thecontents previously filling the measuring chamber 3.

In the device shown in Figures 5 and 6, I have provided a housing 2'that is split and threaded together as at e and in which pins 58,preferably four in number are equidistantly spaced around the chamber 3'to guide the valve I4 upwardly and downwardly 110 open and closedpositions. The pins 50 are preferably secured into the Walls forming thechamber 3 and are spaced from the side walls of va1ve I4 a sufficientdistance that the va1ve I 4 Will be enabled to move upwardh anddownwardly in the measuring chamber 3, regardless of the pivotal andfixed connections between the operating mechanisrn B and the valve I4.

I claim:

1. In a measuring device a housing having an axia1 bore therethrough andmeans of connection with a container; a valve for engagement With oneend of said housing to c1ose the bore therein; a trap door pivotallyconnected to said housing to close the other end of said bore; meansextending through said bore and connect- Ing said trap door and saidvalve; and means to move said trap door 130 close one end of said boreand to move said va1ve away from said housing, said means including ahandle member and means to.move said valve and trap door with a snapaction.

2. In a measuring device, a housing having means for connection with acontainer and a measuring chamber in said device; a Valve normallysealing the contents of said container in said container; a trap dooroperatively associated with one end of said measuring chamber and beingnormally in open position; a link provided with a coiled portionintermediate its ends, said link connecting said trap door and saidvalve; a shaft on which said trap door is pivobally mounted; a handlemember for 0Scillating said shaft; and spring means connecting saidshaft and said trap door to move said trap door to closed position uponoscillation of said shaft, and to open said valve member.
